Abstract
The shutter device has a blade and a frame member which supports the blade in a rotatable manner. The device has a shaft arranged along the frame member, an actuator device for rotating the shaft, and a link member which opens and closes the blade by transmitting a rotational force of the shaft to the blade. The device has a calibration structure having a calibration member formed on the shaft and a calibration surface formed on the frame member. The calibration structure calibrates a rotational position of the shaft by coming into contact with the calibration member onto the calibration surface. The device further has a discharge structure which discharges foreign matters existing between the calibration member of the shaft and the calibration surface of the frame member.
